项目时间：2022.04.18

项目地点：天津

项目介绍：LNG储(chu)配(pei)站(zhan)是由卸(xie)车(che)系(xi)统(tong)(tong)、LNG储(chu)罐(guan)(guan)、增(zeng)(zeng)压(ya)系(xi)统(tong)(tong)、气(qi)化系(xi)统(tong)(tong)、BOG加(jia)(jia)热(re)(re)系(xi)统(tong)(tong)、EAG加(jia)(jia)热(re)(re)及(ji)放空(kong)系(xi)统(tong)(tong)、调压(ya)计量(liang)及(ji)加(jia)(jia)臭系(xi)统(tong)(tong)、自控系(xi)统(tong)(tong)等组成。LNG采用(yong)罐(guan)(guan)式集装箱(xiang)贮(zhu)(zhu)(zhu)存，通过公(gong)路运(yun)至(zhi)贮(zhu)(zhu)(zhu)存气(qi)化站(zhan)，在卸(xie)气(qi)台通过集装箱(xiang)自带的增(zeng)(zeng)压(ya)器(qi)(qi)对集装箱(xiang)贮(zhu)(zhu)(zhu)槽增(zeng)(zeng)压(ya)，利用(yong)压(ya)差将LNG送至(zhi)贮(zhu)(zhu)(zhu)存气(qi)化站(zhan)低(di)温(wen)LNG贮(zhu)(zhu)(zhu)槽。非工(gong)作条件下(xia)(xia)，贮(zhu)(zhu)(zhu)槽内(nei)LNG贮(zhu)(zhu)(zhu)存的温(wen)度(du)为(wei)-162℃，压(ya)力(li)(li)为(wei)常压(ya)；工(gong)作条件下(xia)(xia)，贮(zhu)(zhu)(zhu)槽增(zeng)(zeng)压(ya)器(qi)(qi)将贮(zhu)(zhu)(zhu)槽内(nei)的LNG增(zeng)(zeng)压(ya)到0.35MPa（以下(xia)(xia)压(ya)力(li)(li)如未加(jia)(jia)说明，均(jun)为(wei)表压(ya)）。增(zeng)(zeng)压(ya)后的低(di)温(wen)LNG自流进入主空(kong)温(wen)式气(qi)化器(qi)(qi)，与空(kong)气(qi)换热(re)(re)后转(zhuan)化为(wei)气(qi)态NG并(bing)升高温(wen)度(du)，出口(kou)温(wen)度(du)比环境温(wen)度(du)低(di)－10℃，压(ya)力(li)(li)在0.35Mpa；当(dang)空(kong)温(wen)式气(qi)化器(qi)(qi)出口(kou)的天(tian)然气(qi)温(wen)度(du)达(da)不到5℃以上(shang)时，通过水浴(yu)式加(jia)(jia)热(re)(re)器(qi)(qi)升温(wen)。经加(jia)(jia)臭、计量(liang)后进入输配(pei)管网送入各类用(yong)户。
